"L" lens technology or "DO" technology??

Which one is better?

thx

 

The two are not mutually exclusive.

The L designator refers to the high end optical quality of Canon lenses,
while DO merely refers to a specific type of element within a lense.

 

Canon's DO lenses are part of their 'L' line.. Since DO lenses
are 'L' lenses, it's hard to say which is better.

For a given focal length, the 'L' DO lenses are smaller and
lighter than their non DO 'L' counterparts...

That's the difference.

 

Not true. There are two DO lenses and neither is an L lens.
(400mm f4 DO & 70-300mm f/4.5-5.6 DO).

Which is "better"? Well, the L lenses tend to produce better
images while the DO lenses tend to be a lot more compact.
So it depends upon what is important.
